For various reason I need more control of the router so I installed dd-wrt which I believe is supported by D-link.
After which I was still unable to connect with the PS4 using WPA Personal and Enterprise, I still get the same error which is a surprise and leads me to think its something not related to the firmware controlling the router.
But as a solution, as I have dd-wrt, I have created a controlled access list using the Mac address' so now I can run without wireless security.
